OPML, or Outline Processor Markup Language, is a file format utilized primarily for outlining data structures.

Its uses have expanded over time, notably in organizing RSS feed lists and managing hierarchical data. The OPML file extension denotes XML-based documents that offer simplicity and interoperability in transferring structured information across diverse platforms. In essence, OPML serves as a versatile tool in the realm of data organization and syndication.

Markdown is a lightweight markup language designed to be easily readable and writable, enabling users to format text using simple syntax. These files are widely used for documentation, notes, and content creation due to their simplicity and portability across different platforms and applications.
